CVE-2025-6806

Estado: AnalizadaAlta (7.5)—

Marvell QConvergeConsole decryptFile Directory Traversal Arbitrary File Write Vulnerability. This vulnerability allows remote attackers to create arbitrary files on affected installations of Marvell QConvergeConsole. Authentication is not required to exploit this vulnerability.

The specific flaw exists within the implementation of the decryptFile method. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to write files in the context of SYSTEM. Was ZDI-CAN-24979.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

AV:N/PR:N/UI:N indica acceso remoto sin autenticación (T1190). Directory traversal permite escribir archivos arbitrarios como SYSTEM, causando manipulación de datos (T1565.001) y escalada de privilegios (T1068).

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
